Abstract

Objectives: The aim of this study was to examine the root canal morphology of mandibular molars using cone beam computed tomography images of individuals living in the East of Turkey.Materials and Methods: The tomographic images of a total 183 patients attending the Oral and Maxillofacial Radiology Department and clinical records were taken between 2011-2013 years were evaluated and clinical records. Root and canal diversities were classified according to the methods created by Vertucci and Gulabivala et al.Results: 173 first molar and 235 second molar teeth were examined among evaluated 155 patients. While the majority of the molar teeth had two separate roots (94.2% of the first molars, second molars 81.7%), three separate roots in first molars and second molars were found respectively 4.6% and 2.1%. Mesial roots of first molars with two separate roots showed type 4 canal configuration rate of 72.4%, whereas distal roots showed type 1 canal configuration rate of 69.3%. The Mesial root of the first molar teeth with three canals showed type 2 canal configuration (62.5%), the distal roots showed completely type 1 canal configuration (100%). The rate of 36% for type 4 canal configuration was detected in mesial roots and the rate of 95.8% for type 1 canal configuration was detected in distal roots of second molars with two canals. Type 1 canal configuration was most prevalent in the three rooted molars.Conclusions: While, two separate roots were most prevalent in each of two teeth groups, three separate roots were seen less frequent. Type 1 canal configuration was most prevalent in the distal roots, whereas the mesial roots had more complex root canal morphology and showed mostly type 4 canal configuration

Türkiye’nin doğu bölgesi nüfusundaki mandibular molar dişlerin kök ve kanal yapılarının konik ışınlı bilgisayarlı tomografi ile değerlendirilmesi

Öz

Amaç: Bu çalışmanın amacı Türkiye’nin Doğu bölgesinde yaşayan bireylerdeki mandibular molar dişlerin kök ve kanal yapılarının konik ışınlı bilgisayarlı tomografi görüntüleri kullanılarak incelenmesidir.

Gereç ve Yöntem: 2011-2013 yılları arasında Ağız, diş ve çene radyolojisi kliniğine başvuran ve klinik kayıtları alınan toplam 183 hastanın tomografik görüntüleri değerlendirildi. Kök ve kanal çeşitlilikleri Vertucci ve Gulabivala ve arkadaşlarının oluşturdukları metoda göre sınıflandırıldı.

Bulgular: Değerlendirmeye alınan 155 hastada, 173 tane birinci molar diş, 235 tane ikinci molar diş incelendi. Molar dişlerin büyük çoğunluğu iki ayrı köke (%94.2 birinci molar, %81.7 ikinci molar) sahipken, üç ayrı kök birinci molar dişlerde %4.6 oranında, ikinci molar dişte %2.1 oranında tespit edildi. İki köklü birinci molar dişlerin mezial kökleri %72.4 oranında tip 4 kanal yapısı gösterirken, distal kökleri %69.3 oranında tip 1 kanal yapısı gösterdi. Üç kanala sahip birinci molar dişlerde mezial kök daha çok (%62.5) tip 2 kanal yapısı gösterirken, distal kökler ise tamamen (%100) tip 1 kanal yapısı gösterdi. İki kanallı ikinci molar dişlerde mezial köklerde %36 oranında tip 4, distal kanalda ise %95.8 oranında tip 1 kanal yapısı tespit edildi. Üç köklü olanlarında ise daha çok tip 1 kanal şekli mevcuttu.

Sonuç: Her iki diş grubunda da çoğunlukla ikiye ayrılmış kök yapısı mevcutken, üç ayrı kök daha az sıklıkla görülmektedir. Distal köklerde tip 1 kök kanal yapısı daha yaygın izlenirken; mezial kökler daha karmaşık ve çoğunlukla tip 4 kök kanal yapısı göstermektedir.
